14 | ### 🧑🏻💻 Coding
15 | I tried to write the code of this project as clean as possible and I learned too many thing. The first one i learned to use "get" and "post" methods. The second thing i learned to database operations in nodejs. That's all I was going to tell. Thank you if you are read this text at the moment.
